T. J. McGee (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) – The STROZ lidar retrieves ozone vertical profiles in the stratosphere from 10 to 50 km. Temperature to ~80 km and aerosols (at 355 nm) to 35 km also are measured. The instrument has also been modified to measure water vapor from near the ground to ~15 km. As a mobile intercomparator, it has participated in an ozone intercomparison at Sodankylä during March – April 2006 and in February 2007.
